Initially the United States government tried to cover up the plane's purpose and mission, but was forced to admit its military nature when the Soviet government came forward with the captured pilot and remains of the U-2 including spying technology that had survived the crash as well as photos of military bases in the Soviet Union taken by the aircraft. Coming roughly two weeks before the scheduled opening of an east–west summit in Paris, the incident was a great embarrassment to the United States[2] and prompted a marked deterioration in its relations with the Soviet Union. Powers was convicted of espionage and sentenced to three years of imprisonment plus seven years of hard labor but would be released two years later on 10 February 1962 during a prisoner exchange for Soviet officer Rudolf Abel.[3]

In July 1957, U.S. President Dwight D. Eisenhower requested permission from Pakistan's Prime Minister Huseyn Suhrawardy for the U.S. to establish a secret intelligence facility in Pakistan and for the U-2 spyplane to fly from Pakistan. The U-2 flew at altitudes that could not be reached by Soviet fighter jets of the era; it was believed to be beyond the reach of Soviet missiles as well. A facility established in Badaber (Peshawar Air Station), 10 miles (16 km) from Peshawar, was a cover for a major communications intercept operation run by the United States National Security Agency (NSA). Badaber was an excellent location because of its proximity to Soviet central Asia. This enabled the monitoring of missile test sites, key infrastructure and communications. The U-2 "spy-in-the-sky" was allowed to use the Pakistan Air Force portion of Peshawar Airport to gain vital photo intelligence in an era before satellite observation.[4]

President Eisenhower did not want to fly American U-2 pilots over the Soviet Union because he felt that if one of these pilots were to be shot down or captured that it could be seen as an act of aggression. At a time like the Cold War, any act of aggression could spark open conflict between the two countries. In order to ease the burden of flying Americans into Soviet airspace the idea developed to have British pilots from the Royal Air Force fly these missions in place of the American Central Intelligence Agency (CIA). With the United Kingdom still reeling from the aftermath of the Suez Crisis and in no position to snub American requests, the British government was amenable to the proposal. Using British pilots allowed Eisenhower to be able to use the U-2 plane to see what the Soviet Union was hiding, while still being able to plausibly deny any affiliation if a mission became compromised.

After the success of the first two British pilots and because of pressure to determine the number of Soviet intercontinental ballistic missiles more accurately, Eisenhower allowed the flying of two more missions before the Four Power Paris Summit, scheduled for 16 May. The final two missions before the summit were to be flown by American pilots.[5]

The plane was detected by the Soviet Air Defense Forces when it had flown more than 250 kilometres (155 mi) over the Soviet national boundary and avoided several attempts at interception by a MiG-19 and a Su-9 during the flight. The U-2 left Soviet air space and landed at an Iranian airstrip at Zahedan. It was clear that the U.S. Central Intelligence Agency had successfully performed an extraordinary intelligence operation. The next flight of the U-2 spyplane from Peshawar airport was planned for late April.[6]

On 28 April 1960, a U.S. Lockheed U-2C spy plane, Article 358, was ferried from Incirlik Air Base in Turkey to the US base at Peshawar airport by pilot Glen Dunaway. Fuel for the aircraft had been ferried to Peshawar the previous day in a US Air Force C-124 transport. A US Air ForceC-130 followed, carrying the ground crew, mission pilot Francis Gary Powers, and the back up pilot, Bob Ericson. On the morning of 29 April, the crew in Badaber was informed that the mission had been delayed one day. As a result, Bob Ericson flew Article 358 back to Incirlik and John Shinn ferried another U-2C, Article 360, from Incirlik to Peshawar. On 30 April, the mission was delayed one day further because of bad weather over the Soviet Union.[6]

The weather improved and on 1 May, 15 days before the scheduled opening of the east–west summit conference in Paris, Captain Francis Gary Powers, flying Article 360, 56–6693 left the US base in Peshawar on a mission with the operations code word GRAND SLAM[7] to overfly the Soviet Union, photographing targets including the ICBM sites at the Baikonur Cosmodrome and Plesetsk Cosmodrome, then land at Bodø in Norway. At the time, the USSR had six ICBM launch pads, two at Baikonur and four at Plesetsk.[8]Mayak, then named Chelyabinsk-65, an important industrial center of plutonium processing, was another of the targets that Powers was to photograph.[9] A close study of Powers's account of the flight shows that one of the last targets he overflew, before being shot down, was the Chelyabinsk-65 plutonium production facility.[10]

The U-2 flight was expected, and all units of the Soviet Air Defence Forces in the Central Asia, Kazakhstan, Siberia, Ural, and later in the U.S.S.R. European Region and Extreme North, were placed on red alert. Soon after the plane was detected, Lieutenant General of the Air Force Yevgeniy Savitskiy ordered the air-unit commanders "to attack the violator by all alert flights located in the area of foreign plane's course, and to ram if necessary".[11]

Because of the U-2's extreme operating altitude, Soviet attempts to intercept the plane using fighter aircraft failed. The U-2's course was out of range of several of the nearest SAM sites, and one SAM site even failed to engage the aircraft since it was not on duty that day. The U-2 was eventually brought down near Kosulino, Ural Region, by the first of three SA-2 Guideline (S-75 Dvina) surface-to-air missiles[12] fired by a battery commanded by Mikhail Voronov.[6] The SA-2 site had been previously identified by the CIA, using photos taken during Vice President Richard Nixon's visit to Sverdlovsk the previous summer.[13][14]

Powers bailed out but neglected to disconnect his oxygen hose first and struggled with it until it broke, enabling him to separate from the aircraft. Powers was captured soon after parachuting safely down onto Russian soil.[11] Powers carried with him a modified silver dollar which contained a lethal, shellfish-derived saxitoxin-tipped needle, but he did not use it.[15]

The SAM command center was unaware that the plane was destroyed for more than 30 minutes.[11] One of the Soviet MiG-19 fighters pursuing Powers was also destroyed in the missile salvo, and the pilot, Sergei Safronov, was killed.[6][16] The MiGs' IFF transponders were not yet switched to the new May codes because of the 1 May holiday.[17]

Four days after Powers disappeared, NASA issued a very detailed press release noting that an aircraft had "gone missing" north of Turkey.[3] The press release speculated that the pilot might have fallen unconscious while the autopilot was still engaged, even falsely claiming that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties." To bolster this, a U-2 plane was quickly painted in NASA colors and shown to the media. Under the impression that the pilot had died and that the plane had been destroyed, the Americans had decided to use the NASA cover-up plan.[18]Nikita Khrushchev used the American misstep to embarrass President Eisenhower and his administration.

That same day on May 5, the Senate made its first comments on the U-2 incident, and began a domestic political controversy for Eisenhower. Mike Mansfield, the Senate Majority Whip, stated, "First reports indicate that the President had no knowledge of the plane incident. If that is the case, we have got to ask whether or not this administration has any real control over the federal bureaucracy."[19] Mansfield, more than any other person, highlighted the dilemma Eisenhower faced—Eisenhower could admit responsibility for the U-2 flight, and likely ruin any chances for détente at the Paris Summit, or he could continue to deny knowledge and indicate that he did not control his own administration.[20]

After Khrushchev found out about America's NASA cover story, he developed a political trap for Eisenhower. His plan began with the release of information to the world that a spy plane had been shot down in Soviet territory, but he did not reveal that the pilot of this plane had also been found and that he was alive. With the information that Khrushchev released, the Americans believed that they would be able to continue with their cover story that the crashed plane was a weather research aircraft and not a military spy plane. The cover-up said that the pilot of the U-2 weather plane had radioed in that he was experiencing oxygen difficulties while flying over Turkey. From there they claimed that the plane could have continued on its path because of auto-pilot, and that this could be the plane that crashed in the Soviet Union. The final attempt to make the cover story seem as real as possible was the grounding of all U-2 planes for mandatory inspection of oxygen systems in order to make sure that no other "weather missions" would have the same result as the one that was lost and possibly crashed in the Soviet Union.[21]

I must tell you a secret. When I made my first report I deliberately did not say that the pilot was alive and well ... and now just look how many silly things the Americans have said.

As the trap began to come together, it became clear that Gary Powers was alive and that he had told his mission to the Soviets. Also, because of the release of some photographs of the plane, there was evidence that most of the covert U-2 technologies had survived the crash. From this Khrushchev was able to openly embarrass the Eisenhower administration by exposing the attempted cover-up.[22]

Yet despite Khrushchev's May 7 political trap, the Soviet premier still attempted to allow Eisenhower to save face, possibly to salvage the peace summit to some degree. Khrushchev specifically laid the blame for the U-2 not on Eisenhower himself, but on DCI Allen Dulles and the CIA. Khrushchev said that anyone wishing to understand the U-2's mission should "seek a reply from Allen Dulles, at whose instructions the American aircraft flew over the Soviet Union."[23] On May 9, the Soviet premier told US ambassador Thompson that he "could not help but suspect that someone had launched this operation with the deliberate intent of spoiling the summit meeting." Thompson also wrote in his diplomatic cable that Khrushchev suspected it was Allen Dulles, and that Khrushchev had heard about Senator Mansfield's remarks that Eisenhower did not control his own administration.[24]

Upon receiving this cable, Eisenhower, who frequently was very animated, was quiet and depressed. The only words he said to his secretary were, "I would like to resign."[25] Meanwhile, the domestic pressure continued to mount. Eisenhower then accepted Dulles's argument that the congressional leadership needed to be briefed on the U-2 missions from the last four years. Dulles told the legislature that all U-2 flights were used for aerial espionage and had been flown pursuant to "presidential directives." Still, Dulles played down Eisenhower's direct role in approving every previous U-2 flight.[26]

The next day on May 10, without consulting with any agency heads, House Appropriations Chair Clarence Cannon received considerable press attention when he, not President Eisenhower, revealed the true nature of the U-2 mission. He said to an open session of the House of Representatives that the U-2 was a CIA plane engaged in aerial espionage over the Soviet Union. Cannon said,

Mr. Chairman, on May 1 the Soviet Government captured, 1300 miles inside the boundaries of the Russian empire, an American plane, operated by an American pilot, under the direction and control of the U.S. Central Intelligence Agency, and is now holding both the plane and the pilot. The plane was on an espionage mission ... The activity ... [was] under the aegis of the Commander in Chief of the Armed Forces of the United States, for whom all members of the subcommittee have the highest regard and in whose military capacity they have the utmost confidence.[27]

At the end of Cannon's speech, Democrats and Republicans uncharacteristically rose to their feet to applaud.[28]

Still Eisenhower faced criticism in the press for not controlling his own administration, as Cannon's speech only said the mission was "under the aegis of" the president, not "directed by." Press reports were creating a belief in the public that Eisenhower had lost control, which Eisenhower would not let stand. Knowing that he was jeopardizing the Paris Peace Summit, Eisenhower decided to reveal the aerial espionage program and his direct role in it, an unprecedented move for a U.S. President. His speech on 11 May revolved around four main points: the need for intelligence gathering activities; the nature of intelligence gathering activities; how intelligence activities should be viewed (as distasteful, but vital); and finally that Americans should not be distracted from the real problems of the day. Eisenhower closed passionately by reacting to the Soviet claim that the US acted provocatively and said: "They had better look at their own [espionage] record." As he finished, he told reporters he was still going to the Paris Peace Summit.[29]

Contemporary reactions to the U-2 incident and effect on the Four Powers Summit[edit]

The Summit was attended by then president of the United States Dwight D. Eisenhower, Soviet premier Nikita Khrushchev, French president Charles de Gaulle, and prime minister of the United Kingdom, Harold Macmillan.[31] It was the first conference to be attended by both Soviet and western leaders in five years.[32] However, prospects for constructive dialogue were dashed by the explosive controversy surrounding the U-2 flight over Soviet territory.

Although the Four Powers Summit was the first meeting between western and Soviet leaders in five years when it was held, the mood was optimistic that there could be an easing of tensions between the Soviet Union and the United States. In an effort to present a less hostile, more cordial Soviet Union, Khrushchev publicly advocated a policy of "peaceful coexistence with the United States."[32] The May Day celebrations on 1 May of that year were marked by this newfound cooperative spirit. Absent were the militarized symbols of previous parades, such as artillery and armor. Instead there were children, white doves, and athletes.[33] But the reaction of the Soviet government to the spy plane incident and the response from the United States doomed any potential meaningful peace agreement.[31]

In the days directly leading up to the conference, tensions increased dramatically between the United States and the Soviet Union over the U-2 incident. At this point in the negotiations, the hardliners of the Soviet government were applying heavy pressure to Khrushchev.[34] In the weeks leading up to the summit there had been a revitalization of anti-American sentiment within the Kremlin,[34] with the Soviets blocking a planned trip to Washington D.C. of a Soviet air marshal, inviting Chinese communist leader Mao Zedong to Moscow, and launching an anti-American press campaign designed to critique "American aggression."[34] At this time east and west were divided about how to move forward in Berlin, and the American press characterized Khrushchev's decision to emphasize the U-2 incident at the summit as an attempt to gain leverage on this issue.[35]

The summit itself did not last long, with talks only beginning on 15 May and ending on 16 May. Both Eisenhower and Khrushchev gave statements on the 16th. Khrushchev blasted the United States on the U-2 incident. He pointed out that the policy of secret spying was one of mistrust and that the incident had doomed the summit before it even began. He expected the United States and Eisenhower to condemn the spying and pledge to end further reconnaissance missions.[36]

At the summit, after Khrushchev had blown Eisenhower's cover, Eisenhower did not deny that the plane had been spying on Soviet military installations but contended that the action was not aggressive but defensive. He argued that the current state of international relations was not one in which peaceful coexistence was an already established fact. The policy of the United States towards the Soviet Union at that time was defensive and cautionary. Eisenhower also made the point that dialogue at the Four Powers Summit was the type of international negotiation that could lead to a relationship between the United States and the Soviet Union where there would be no need to spy on each other.[36] Eisenhower also laid out a plan for an international agreement that authorized the U.N. to "inspect" any nations willing to submit to its authority for signs of increased militarization and aggressive action. He stated that the United States would be more than willing to submit to such an inspection by the U.N. and that he hoped to circumvent the spying controversy with this alternative international surveillance agreement.[36]

The meeting during which both parties made their statements lasted just over three hours. During this time Khrushchev rescinded an invitation he had earlier given to Eisenhower to visit the Soviet Union.

According to Walter Cronkite, Khrushchev would go on to say that this incident was the beginning of his decline in power as party chairman, perhaps because he seemed unable to negotiate the international arena and the communist hardliners at home.[32] The collapse of the summit also saw an increased tension between the Soviets and the Americans in the years to come. After this debacle the arms race accelerated and any considerations for negotiations were dashed for the immediate future.[37]

As a result of the spy plane incident and the attempted cover-up, the Four Power Paris Summit was not completed. At the beginning of the talks on 16 May, there was still hope that the two sides could come together even after the events that took place earlier in May, but Eisenhower refused to apologize and Khrushchev left the summit one day after it had begun. Some people[who?] said that Khrushchev had overreacted to the event in an attempt to strengthen his own position, and for that, he was the one to blame for the collapse of the Four Power Paris Summit.[22]

Before the U-2 incident Khrushchev and Eisenhower had been getting along well and the summit was going to be an opportunity for the two sides to come together. Also, Eisenhower had been looking forward to a visit to the Soviet Union and was very upset when his invitation was retracted. The two sides were going to discuss topics such as nuclear arms reduction and also how to deal with increasing tensions surrounding Berlin. According to Eisenhower, had it not been for the U-2 incident the summit and his visit to the Soviet Union could have greatly helped Soviet and American relations.[38]

The Soviet Union convened a meeting of the United Nations Security Council on 23 May to tell their side of the story.[39] The meetings continued for four days with other allegations of spying being exchanged, as well as recriminations over the Paris Summit, and a US offer of an "open skies" proposal to allow reciprocal flights over one another's territory,[40][41][42] at the end of which the Soviet Union overwhelmingly lost a vote[43] on a concise resolution which would have condemned the incursions and requested the US to prevent their recurrence.[44]

The incident severely compromised Pakistan's security and worsened relations between it and the United States. As an attempt to put up a bold front, General Khalid Mahmud Arif of the Pakistan Army, while commenting on the incident, stated that "Pakistan felt deceived because the US had kept her in the dark about such clandestine spy operations launched from Pakistan's territory."[45] The communications wing at Badaber was formally closed down on 7 January 1970.[46] Further, the Senate Foreign Relations Committee held a lengthy inquiry into the U-2 incident.[47]

Upon his capture, Gary Powers told his Soviet captors what his mission had been and why he had been in Soviet airspace. He did this in accordance with orders that he had received before he went on his mission.[38] Powers pleaded guilty and was convicted of espionage on 19 August and sentenced to three years imprisonment and seven years of hard labor. He served one year and nine months of the sentence before being exchanged for Rudolf Abel on 10 February 1962.[3] The exchange occurred on the Glienicke Bridge connecting Potsdam, East Germany, to West Berlin.[48]

The incident showed that even high-altitude aircraft were vulnerable to Soviet surface-to-air missiles. As a result, the United States began emphasizing high-speed, low-level flights for its previously high altitude B-47, B-52 and B-58 bombers, and began developing the supersonic F-111, which would include an FB-111A variant for the Strategic Air Command.[49] The Corona spy satellite project was accelerated. The CIA also accelerated the development of the Lockheed A-12 OXCART supersonic spyplane that first flew in 1962 and later began developing the Lockheed D-21unmanned drone.[citation needed]

The original consensus about the cause of the U-2 incident was that the spy plane had been shot down by one of a salvo of 14 Soviet SA-2 missiles. This story was originated by Oleg Penkovsky, a GRU agent who spied for MI6.[50] In 2010, CIA documents were released indicating that "top US officials never believed Powers's account of his fateful flight because it appeared to be directly contradicted by a report from the National Security Agency" which alleged that the U-2 had descended from 65,000 to 34,000 feet (19,812 to 10,363 m) before changing course and disappearing from radar. One contemporary reading of the NSA's story is that they mistakenly tracked the descent of a MiG-19 piloted by Sr. Lt. Sergei Safronov.[51]

In 1996, Soviet pilot Captain Igor Mentyukov claimed that, at 65,000 feet (19,800 m) altitude, under orders to ram the intruder, he had caught the U-2 in the slipstream of his unarmed Sukhoi Su-9, causing the U-2 to flip over and break its wings. The salvo of missiles had indeed scored a hit, downing a pursuing MiG-19, not the U-2. Mentyukov said that if a missile had hit the U-2, its pilot would not have lived.[52][53]

Though the normal Su-9 service ceiling was 55,000 feet (16,800 m), Mentyukov's aircraft had been modified to achieve higher altitudes, having its weapons removed. With no weapons, the only attack option open to him was aerial ramming. Mentyukov asserted that Soviet generals concealed these facts to avoid challenging Nikita Khrushchev's faith in the efficiency of Soviet air defenses.[53]

In 2000, Sergei Khrushchev wrote about the experience of his father, Nikita Khrushchev, in the incident. He described how Mentyukov attempted to intercept the U-2, but failed to gain visual contact. Major Mikhail Voronov, in control of a battery of anti-aircraft missiles, fired three SA-2s at the radar contact but only one ignited. It quickly rose toward the target and exploded in the air behind the U-2 but near enough to violently shake the aircraft, tearing off its long wings. At a lower altitude, Powers climbed out of the falling fuselage and parachuted to the ground. Uncertainty about the initial shootdown success resulted in 13 further anti-aircraft missiles being fired by neighboring batteries, but the later missiles only hit a pursuing MiG-19 piloted by Sr. Lt. Sergei Safronov, mortally wounding him.[17] This account of the events that occurred during the mission match the details that were given to the CIA by Gary Powers. According to Powers, a missile exploded behind him and after this occurred his U-2 began to nosedive. It is at this point that Powers began to make all of the preparations to eject. Powers landed safely and tried to hide himself in the Russian countryside until he could get help. His attempts to do this failed and he was captured.[21] Sergei Safronov was posthumously awarded the Order of the Red Banner.[11]

In 2015 the Steven Spielberg feature film Bridge of Spies was released, which dramatized James B. Donovan (Tom Hanks[54])'s negotiations for Powers' release, but took certain liberties with what really happened. For instance, Powers is shown being tortured by the Soviets, when in reality he was treated well by his captors and spent much of his time doing handicrafts.[55] In the film, a television reporter say the U-2 is a NASA aircraft.

In January 2016, the BBC magazine produced photographs from the time and an interview with Powers's son.[56]

^Amjad Ali, the Pakistani ambassador to the US at the time, narrated in his book Glimpses (Lahore: Jang Publishers, 1992) that the personal assistant of Suhrawardy advised embassy staff of the Prime Minister's agreement to the US facility on Pakistan soil.
